Three MCAS Questions ●2 Which of the following matches a cell organelle with its function? A. chloroplast—movement B. nucleus—cell regulation C. vacuole—energy production D. mitochondrion—photosynthesis 2.1 Relate cell parts/organelles (plasma membrane, nuclear envelope, nucleus, nucleolus, cytoplasm, mitochondrion, endoplasmic reticulum, Golgi apparatus, lysosome, ribosome, vacuole, cell wall, chloroplast, cytoskeleton, centriole, cilium, flagellum, pseudopod) to their functions. Explain the role of cell membranes as a highly selective barrier (diffusion, osmosis, facilitated diffusion, active transport). ●23 DNA is found in the cells of all organisms. The structure of DNA is directly linked to its function. a. Describe the function of DNA in organisms. b. In your Student Answer Booklet, draw and label a simple model of DNA that includes the sugar/phosphate backbone and nitrogenous bases. c. Explain how the structure of DNA enables it to perform the function you described inpart (a). 3.1 Describe the basic structure (double helix, sugar/phosphate backbone, linked by complementary nucleotide pairs) of DNA, and describe its function in genetic inheritance. ●38 Which of the following processes produces the nucleotide sequence UUA from the sequence AAT? A. meiosis B. replication C. respiration D. transcription
